A building collapsed in downtown Philadelphia on Wednesday onto a neighboring two-story Salvation Army Thrift Store at 2140 Market Street at 10:45 a.m., trapping people under debris, Ayers said. and rescue workers pulled 14 people from mountains of crushed concrete and splintered wood, using search dogs to scour the rubble for others, fire officials said

Those pulled from the rubble suffered minor injuries and were taken to area hospitals where they were in stable condition, he said.

One witness, Dan Gillis, 31, of Cinnaminson, New Jersey, a construction worker on a job across the street, told Reuters he saw a crane remove a supporting beam from the front of the building, and then the wall next to the thrift store started swaying.
